SPECIFICATION forming para ofneteersratent N'o. esseenuatea November App'umtoqmed August 27, nes. (No model To" all whom) it .7n/ay concern:

Be it known that I, GERGE Escort, Jr.,

"a citizen ofthe United States, anda resident of Moorestown, uBurlingf'ton county, New .Ter-

. sey, have invented certain Improvements in specification. y

My invention relates" to improvements in that class of `milk-cans which are provided with inner and outer covers; and the main object of my invention' is to so combilie amill-j llIill -Can Tops, of which the following is can top with an inner'` cover and a hinged outer cover, and with appliances explained hereinafter, that the covers may be fastened simultaneously and unfastened simultaneously. p

Other objects of my invention and devices "for carrying them into effect are too fully eX- plained hereinafter toneed preliminary description.

Further objects of my invention are to af-A Aford opportunities for locking the covers, and

for sealing the outer cover. y

In the accompanying drawings, Figure 1, Sheet 1, is a vertical section of my milk-can top, Fig.2, a plan View; Figf, aview showing the character of the opening in the outer l cover;` Fig. 4, Sheet 2, a sectional view ofthe milk-can top as it appears when the covers y 5, a sectional plan on the line 12, Fig. 1.

have been opened and turned back; and Fig.

A casing, A, preferably of cast-iron, has at its lower edge an annular flange, a, which is secured to the sheet-metal body of a milk-can, the said body being similar to those of cans in common use for the transportation of milk.

The casing A has an internal annular flange,

` b, having a trued upper surface, forming a bearing for the trued under surface of the innergcover, D, the latter having 1on its upper surface, near the outer edge, three, or any other appropriate'number of inclined planes,

` f m, (shown in Fig. 5,) which, by turning the cover, can be brought beneath lugs or ribs d on the interior of` the casing, thereby locking the said inner cover to the internalrib, b, and forming therewith a tight oint. This inner cover has at its edge as many notches d as there are `lugs d, so that when the former co- 1" l 5o incide with the latter the cover may be lowered onto or raised from the flange 1b.

13, ieee;-

A central stem, E, extends upward from inner' cover, D, through an outer cover, F,

which is hinged at y to the casing A, the stem Vis in contact with the outer cover, and both covers may then be turned back to the posi# tion shown in Fig. 4.

, The stem E has` a flange or collar, 1),. which preventsthe cover F from being raised until the inner cover is in a given positionlthat is, when it `is unlocked from the lugs din the casingan`d when the notches in the edge i' the inner cover coincide with the said lugs then` theinner cover can be elevated, for arib, e, on the stem E can pass through and slide in" a notch, z', in the opening L, Fig. 3, of theouter cover; but when the covers are depressed the outer cover is clear of the upper end of `the rib c, and the stem E and inner cover can be turned and locked, the outer cov'er being at the same time locked, owingto the flange c Vof the stem. j Y

The object of the rib e is to facilitate the adjustment of the inner cover to its place in. lowering it and preparatory to locking. The outer cover cannot be raised until the upper end of the said ribe coincides with the notch vl in the edge of the opening of the outer cover, F, and

as long as the inner cover is elevated it is prevented by the rib from turning, and in lowering the inner cover it is so guided by the rib that the notches in the edge of the cover will coincide with lugs d in the interior of the cas-` and locking of the inner. cover. f

rIhe pilferingof milk from cans during transportation is a common occurrence;` hence I secure the covers in such a manner that milk cannot be abstracted from the can without detection. I pivot tothe upper end of the stem E an arm, G, and when this arm occupies a position between the two projections m` m on theouter cover, F, it is an indication that the covers are in a condition to be raised and' turned back; but in preparing a filled can for transportation I turn the stem E of the inner cover until the latter is tight to its bearings, and the can thereby sealed, when the arm G will be near but not generally in contact with a projection, p', on the said outer cover, and the armv can then be bound to this projection by passing a wire or cord through holesin both and properly fastening the same, so that there can beno dislodgement of the inner cover from its seat until the removal of the fastening. A proper seal may be attached to the cord or Wire, so as to indicate any attempt to unfasten it; but there are occasions when the can should be closedwithout being sealed,

so as to be promptly opened, as, for instance,

when the can is at its destination; hence the intermediate projection, p, on the cover.

` When a portion of the contents of the can has been removed, and it is desirable to properly close the same, the .stem is turned until the arm G, the latter being raised, has crossed the rintermediate projection, p, which, when the arm is released, will retain the cover in asubstantially' closed condition without said cover being tightly bound to itsseat.

a stem, E, passing through the outer cover, Y

and provided with a rib, e, adapted to a notch in the said cover, and with a flange or collar, o, by and between which and the upper end of the rib the said cover maybe confined, sub-l stantially as described.

3. The combination of the casing A, the outer cover, F, hinged thereto, and having projections m m, the inner cover, D, constructed to be locked to and released from a bearing in the casing, and having a stem, E, passing through and constructed to lock Yand release the outer cover, and having a pivoted arm, G, adapted to fit between the said projections, substantially as set forth.

4. The combination of the casing A, having a flange, b, and projection d, and the outer cover, F, hinged to the said casing, and having projections p p, with the notched inner cover having inclined planes w, and a stem, E, passing through the outer cover, with the arm G, pivoted to the stem, all substantially as specified. v

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
